Question

Which of the following is the linear species?

$N_{2}O$ and $S{O}_2$

Answer 1

In $N_{2}O$ the hybridization of both the $N$ is $sp$ because the terminal $N$ has one sigma bond and one lone pair and the central $N$ has 2 sigma bond therefore the structure is linear whereas in $S{O}_2$ the central $S$ atom forms 1 sigma bond with each $O$ atom and there is one lone pair therefore the hybridization is $s{p}^2$ and hence it is $V$ shaped molecule. Therefore the correct answer is $N_{2}O$.
